摘要： There is described a ventilator for providing breathable air to a patient. The ventilator includes an airbag defining a longitudinal axis, having a first end, a second end, and a foldable wall extending from the first end to the second end, and being movable from a decompressed state to a compressed state by moving the first end along the longitudinal axis relative to the second end. The wall has fold lines formed therein such that, during movement of the airbag from the decompressed state to the compressed state, the wall is folded along the fold lines. The fold lines define at least one polygonal surface portion of the wall. The ventilator further includes an actuator for driving compression and decompression of the airbag, and a controller for controlling the actuator.
